SPECIFICATION forming part of Letters Patent No. 267,712, dated November 121, `1882.

Application filed September 19, 1882. (No model.)

To all whom it may concern:

Beit known that I, OLE PEDERsoN, of Golnmbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Furniture-Casters; and I do hereby declare the following to be a full, clear, and exact description, reference being hadto the accompanying drawings, making a part of this specification, in which- Figure 1 is a perspective view of acaster with my improvements attached. Fig. 2 is a section through X X of Fig. 1. Fig. 3 is a rear elevation, with oneof thelarge wheels removed. Fig. 4 shows the grooves in the stein to receive the pieces of Wood. Fig. 5 shows a side elevation of the shank.

My invention relates to certain improvements in furniture-casters, and is an improvement on Patent No. 218,565, issued to me August 12,1879; and it consists in the several combinations of devices hereinafter explained and claimed.

To enable others skilled in the art to make and use my invention, I will proceed to describe the exact manner in which 1 have carried it out.

In the drawings, A is the shank ofthe cast- Ihis shank is provided with the collar C and step G to sustain the stem D. The shank is also provided with bearings a a, against which the large wheels play and by which these wheels are held in place. The bearing a has theshape of an inverted T, as shown in Fig. 2. 'The spaces b in the bearing a hold the upper part of the tlange of the large wheels E, as shown in Figs. l and 2. In Order to give these wheels sufcent play to secure proper oscillation to the caster and to prevent the inner wheels, E', from binding, the spaces bare made wider than the thickness ot' theiiange e. Thelarge Wheels E are held in position around the axle B by means of inner wheels, E', secured to the axle and bearing against the flange @,and by the flange c running in the space b, as shown in Fig. 2. The wheels E and E have independent movements, the former having backward and forward play and being revolved by its contact with and friction on the licor, while thelatter,titting on and bein gattached directly 5o to the axle, is provided with a neck, c', which projects through the large wheel and is revolved by its contact with and friction on the inner periphery of the large wheel, as shown in Fig. l. By this construction I secure an anti-friction caster, as when the large wheel E meets with any obstruction and is temporarilyy arrested in its revolution theinner wheel con-k tinues to revolve until the large wheel is relieved.

The stem F may be either cast or drawn from wrought-iron, and is provided with one or more spaces,f, on its sides for tlieinsertion ot' strips or piecesfl of wood. These pieces of wood may be secured in the spaces f in any convenient Way. I prefer making transverse dovetail grooves, asshown in Fig. 4, and fitting into them the pieces ot' wood. The object of this construction of the -stem is to enable me to firmly secure the caster to the furniture by glue. I simply dip the stenl in glue and then place it in the hole prepared to receive it. The shank is secured to the stern by means of groove c' around the stem, into which the lip t" on shank is forced; or the stein provided with the groove may be placed in the mold and the shank cast over it, as" described in my patent before referred to.

Having thus described my invention. what I claim as new, and desire to secure by Letters Patenti, is-

1. In a furniture-caster, the inner Wheel, E', and the shank A, provided with the axle B, in combination with the large wheels E, all constructed to operate substantially as and for the purpose set forth.

2. The shank A, provided with the axle B and bearings aa', in combination with the wheelsE E and a stem, substantially as and y for the purpose set forth.

3. In a furniture-caster, the stenr F, provided with spaces or recesses for securing strips of wood, substantially as and for the purpose set forth.
